Abstract/Contents:"Field and growth chamber studies have been carried out on Kentucky bluegrass (Poa pratensis L.) red fescue (Festuca rubra L.) and Penncross bent grass (Agrostis palustris Huds.) on the suitability of various chemicals as growth regulators. The effects of chemicals such as maleic hydrazide (M.H.) and chloroflurenol have been compared with the effects of newer compounds such as MBT 12325-9 (N-(2,4-dimethyl-5-((trifluoromethyl) sulfonyl) amino) phenyl) acetamide and CME 10951-P (a formulation of chloroflurenol) when used alone or in various combinations, or in mixtures with herbicides. The effects of various dates of treatment and rates of chemical on shoot elongation, root growth and seed head formation have been investigated. Best grass suppression with minimum discolouration was obtained from MER 12325-9 at 0.5 kg/ha applied once early in the spring (immediately after the first mowing). A repeated application with this chemical one month later brought about excessive discolouration of the turf. Seed head formation was essentially eliminated by this treatment. The addition of chloroflurenol to MER 12325-9 did not appreciably increase its growth retardation effects. The addition of the herbicides dicamba and 2,4-D had no effect on the activity of the MBR compound and excellent weed control as well as good growth retardation was obtained at rates of 0.5 + 0.5 + 1.0 kg/ha. (MBR + dicamba + 2.4-D)."
